Idk. I don't have a PHD, but 220V sounds like 240V to me. I wouldn't do this.
I feel like getting advice about how to wire up electronics should not be so hard.
> Maybe they should just improve their product to make it more resiliant
Adding "resilience" usually adds to the per-unit cost. I think making a web page adds some cost too, but at least that can be amortised.
> And no matter what happens, customer support should help the customer, not blame them.
I think that's happening here: Making a web page to educate future customers seems like a really good idea. I wouldn't have thought that necessary until I saw it, but I'm always excited to learn something new.
The existing customers who did dumb should consider this a relatively cheap education in electronics; cheaper than a PHD at least!
Also, whether the company also gave them rebates or credits we don't know here, but telling "customer support" they "should help the customer" is also telling them they're not helping the customer, and you don't know that.
- delusional 1y ago> Making a web page to educate future customers seems like a really good idea I don't think this is an official website of ecoflow. Other than that I agree. I don't think asking for a bit of knowledge from the customers is a bad thing. A warning in the manual about safety factors should be enough.
- xenadu02 1y agoThey're just being cheap. If you're going to let customers plug panels directly into your box you should have overvoltage protection. It's that simple.
- cornholio 1y ago> Adding "resilience" usually adds to the per-unit cost. In this case, the cost is much less than a dollar (say, a varistor that blows the existing fuse) and it prevents a catastrophic failure.
- immibis 1y agoBut they want you to have to buy another one.
- hyperhello 1y agoWhy does this kind of comment get downvoted that pinpoints the actual motivation? We just pretend that planned obsolescence is history.
- majorchord 1y agoAt least in parent's case, probably because the vast majority of their comments are black-and-white hot takes that are always downvoted regardless. And they basically never respond when asked for any sources.
- jama211 1y agoBecause it’s an extreme claim backed up with no evidence. Hanlon’s razor applies here.

- saghm 1y agoTo me, 220 sounds 20 like lower than 240. I have a hunch that this might be a common perception.
- geocar 1y agoReally? I have all sorts of electronics that say everything from 208V - 240V that all go in the wall, so I think all those numbers are probably close to each other in whatever a volt is. I think if I'm worried about a limit of some kind, being within 5% of that limit seems like I might as well be over-limit if the commonly seen distribution I see in my house is greater than 15%
- cjbgkagh 1y agoI have a lot of electronics that accept 100-240v doesn’t mean I think they’re close together, just that they have compensating mechanisms to handle such voltages. The margins are generally lower for higher power devices because the electronics are more expensive. Thankfully these electronics in general are becoming cheaper which is one reason why they’re ending up in the hands of people inexperienced with them. Also try to tell someone they need an extra 30% in margin and often they'll think they’re being upsold.
- geocar 1y ago> I have a lot of electronics that accept 100-240v doesn’t mean I think they’re close together, just that they have compensating mechanisms to handle such voltages. I bet you also have a lot of electronics that don't though, and those that do probably say so. My kitchen mixers, dishwasher, washing machine, driers, rice cooker, refrigerators, sauna, and pool pump aren't that tolerant by a long shot. I've got a few computers with a switch on the back to choose between 220v and 110v. Plugging something that takes 110v into my house breaks the thing, so I've learned to check. But I don't have anything that's 208v that can't go into the house. So I think whatever the situation is with volts, within 15% is "basically the same", so coming within 15% of the rated limit, is probably just like exceeding the limit by 15%. And so this is why I would not expect something at 146V to be under the safety limit of 150V. > Also try to tell someone they need an extra 30% in margin and often they'll think they’re being upsold. Where do you get 30%?
- numpad0 1y ago> Idk. I don't have a PHD, but 220V sounds like 240V to me. I wouldn't do this. 220[Vrms] * 1.414 = 311[Vp-p] btw. HOW!?
- rzzzt 1y agoAC wiggles and wobbles.
- mazurnification 1y agoSo the issue is that 220V is nominal in China, 230V nominal in UE and 240V is UK/part of Australia. So if anyone is preparing product for global market (as most are doing now) more likely then not will support all of this voltages. Thus is kind of normal (but wrong) to assume 220V sounds like 240V.
- gus_massa 1y agoMany charguers are now 100-240V, 50-60Hz, that is close to pluggable anywhere on Earth. (I burned one or two a long time ago, when I forgot to check and used a 120V transformed here with 220V)
- rzzzt 1y agoSame thing happened to PC PSUs. I don't think there is a recent unit that still has the self-destruct voltage selector switch which pops them if you are in 230V land (and the switch is set to the smaller setting).
- adrian_b 1y agoWhen the voltage was unified in UE, the nominal value was set to the median of 230 V, but its tolerance was raised from 10% to 15%, so that the new maximum peak value of 230V + 15% will match the old value of 240 V + 10%. So now for all 220/230/240 V standards you have the same maximum voltage value that is used for electrical designs (about 265 V effective), so they are equivalent, regardless of the name.
